It is a magnesium deficiency. Just add some cal mag or epsom salt, but lighten up on nitrogen.

Is this a Magnesium Deficiency?
Hi all, Day 98. Northern Lights. 1 of my 3 NL girls looks to have a bit of a Mg deficiency. I'm close to harvest so not too worried however it would be nice to have a confirmation for future grows/learning as I'm very much a noob still.

Help the rookie w/ a possible calmag deficiency?
Does this look like a calmag deficiency? Link to my journal entry for settings/water param/etc for these to see if you can spot the issue? https://growdiaries.com/diaries/187101-grow-journal-by-mrlahey. Using TDS 0-2 ppm ro/di water with calmag additive.

Intervenial chlorosis, thick wrinkled leaves. Ph imbalance or quantity of nutes? Will adding CaliMag back in help? Trying to avoid burnt tips issue
Hard water (7) lowered to 5.8. Last week: 1 gal 3 waterings, w FloraGro (2.5 ml), Micro (2 ml), Bloom (2.5 ml/), Hydroguard (2 ml). Last grow had burnt tips and possible N deficiency, so I was trying to avoid that. This week I've switched to GHE's schedule and added CaliMag.

Leave color normal?? [First timer]
I am not sure about the color of the leaves if they look normal? The baby leaf seems to be turning a bit yellow. The rest of the leaves seem to be a bit discolored as you can see in the pictures but mainly green though. Is this alright or am I doing something wrong here?

Zombie 6 as shown above in day 20 has a weird light green color forming out the middle. Is this an issue or simply the genetics (Mixed bag so unidentified auto)?

Yellow stains on bottom leaves (indoor grow)
On day 25 yellow stains have appeared on the bottom leaves of two plants (critical 2.0). We don't know from what these stains are coming. On one of these plants, some leaves have also started to develop white dots. Spiders maybe ? Thank you.

I’m not sure if it’s the genetics or what but some leaves are developing a purple hue with some yellow. The new leaf growth doesn’t have it but any input is appreciated. I’ll post a pic in my diary. Thanks!

Yellow streaks between leaf veins
All three of my plants have light green/yellow streaks in between the veins on the leaves that have been present since about week one (week 3 currently). Could this be a magnesium nutrient deficiency, PH issue, or perhaps just overwatering?

Leaves growing differently, some of them with more difficulty
Why some of the largest leaves look like they laterally grow smaller and with some different shades of green? There's a lighter shade between the veins and darker spots, meaning that they are actually still growing? thank you in advance :)

Yellowing on lower, older leaves. Starts with crispy tip, curling downwards then slowly progress to the whole leaf. The leaves haven't started falling off yet but I feel if it doesn't get resolved soon then this will be the next step. Thanks for the help.
